pyGtranslator

A desktop translator using Google Translate

There is no question, Google Translate is one of the fastest and most accurate programs in its niche. Because of that, many desktop translators use it as a foundation for better service.

pyGtranslator is a desktop translator that works hand-in-hand with Google's translator to offer translations that are both clean and comprehensable.

It includes a database of more than 50 different languages that it can translate in either direction: English, French, German, Spanish, Portuguese, Italian, Chinese, Russian, Polish, Japanese, Catalan, Galician, etc.

pyGtranslator also has a Swap button similar to Google Translate (it'll let you change the meaning of the translation) and you can hide it in your system tray for fast access.
